1. Filɛri granular media: musaka fanga kunba-filtration effectif .
Filɛri granular media ye filɛri suguya ye min bɛ kɛ ka caya, min bɛ ji saniya kosɛbɛ farikolo adsorption ni interception fɛ. A suguya minnu bɛ sɔrɔ tuma caman na, olu ye:
1). Quartz cɛncɛn : fɛnɲɛnamafagalan hakɛ 0,5-1,2mm, asidi barikama ani alkali resistance, musaka dɔgɔman, min bɛ kɛ tuma caman na ji minta furakɛli ɲɛfɛ ani nɔgɔ furakɛli la (aw ye "Industrial Water Treatment Technology Manual" lajɛ).
2). Kabɔn min bɛ baara kɛ: A tilalen don kɔɔri ni coco shell ye, ni porosity bɛ se 500-1500m2/g ma (data source: US Environmental Protection Agency), o bɛ se ka fɛnɲɛnamafagalanw ni nɛgɛ gɛlɛnw minɛ, minnu bɛnnen don ji saniyalanw ma ani fiɲɛ saniyacogo ma.
3). Anthracite : densité dɔgɔman (1,4-1.6g/cm3), o faralen don ɲɔgɔn kan ni quartz cɛncɛn ye walasa ka filɛri kɛcogo ɲɛ, a fanba bɛ kɛ filɛri tanki fila la minnu bɛ kɛ ni fɛn fila ye.
Filɛri granular media nafa ye ko a ka nɔgɔn ka compact kɛ wa a mago bɛ kɔko la tuma bɛɛ, ni a si bɛ san 3-5 ɲɔgɔn bɔ.
2. Fibre Filter Material: Filtration ka ɲɛ ani ka ɲɛ .
Fibre filter matériel bɛ dilan ni fɛn ye min bɛ se ka wuli ka bɔ a nɔ na, a ka tiɲɛni ka bon. Lasigiden suguya minnu bɛ yen olu ye:
1). Fibre polypropylene : corrosion- bɛ se ka kɛ PP cotton filter element ye, pore hakɛ 1-10μm, min bɛ kɛ ka so ji saniyalanw fa ka kɔn.
2). Glass fibre : min bɛ se ka funteni caman sɔrɔ ( a ka dɔgɔ walima a bɛ bɛn degere 280 ma ), a ka ca a la, a bɛ kɛ gazi tiɲɛnenw furakɛli la, i n’a fɔ kuran sɛnɛyɔrɔw ka desulfurization system.
3). Seramiki fiyɛli : A faralen don ɲɔgɔn kan ni fɛnɲɛnamafagalanw ni fiɲɛ jogo ye, a bɛ se ka nɔ bila a la kosɛbɛ, a bɛnnen don ka jifilen jilama caman sɔrɔ kemikɛli baara la.
Fibre filter matériel nafa ka dɔgɔ, a kari ka nɔgɔn a baara jan kɔfɛ-waati la, wa a ka kan ka bila a nɔ na tuma bɛɛ.
3. Membrane filɛriw ani fɛnw minnu bɛ bɔ kɛnɛ kan: Fɛɛrɛ kuraw baarakɛcogo .
1). Filɛri min bɛ kɛ ni membrane ye:
- Microfiltration membrane (0,1-10μm): Aw bɛ banakisɛw ni fɛn minnu bɛ wuli, olu bɔ, i n’a fɔ du kɔnɔ ji saniyalanw laban.
- ultrafiltration membrane (0.01-0.1μm): A bɛ se ka banakisɛw bali ani a bɛ kɛ ka caya furakɛli diyalizi la (aw ye "membrane separation technology application guide" lajɛ).
2). Porous ceramic filter media: High temperature resistant (>1000 degɛrɛ ), a bɛ se ka sɔgɔ, nka a musaka ka bon, a fanba bɛ kɛ gazi saniyacogo la min bɛ kɛ ni funteni ye nɛgɛko la.
3). Filɛri kɛcogo kura : i n’a fɔ grafɛnɛ sɛgɛsɛgɛlikɛlanw sɛmɛntiyalen, adsorption se bɛ bonya ni siɲɛ 3 ni kɔ ye ("nature materials" 2022 ɲinini), nka a ma jago kɛ fɔlɔ kosɛbɛ.
4. Filɛri kɛcogo ɲuman sugandi cogo di?
Jateminɛ bɛɛ lajɛlen min sinsinnen bɛ filɛri kuntilenna kan (i n’a fɔ turbidité bɔli, sterilisation, decolorisation), fluid properties (PH nafa, funteni) ani musaka budget. I n'a fo:
- "Kɛrɛnkɛrɛnnen + Karɔbɔni min bɛ baara kɛ" faralen ɲɔgɔn kan, o bɛ kɛ ka caya ji jiriw la;
- ji ultrapure min bɛ ɛntɛrinɛti baarakɛyɔrɔ la, o ka kan ka bɛn ni membrane filɛriw ye;
- seramiki filɛriw ka fisa ni gazi ye min bɛ wele ko gazi bɔli funteni caman na.
Don nataw la, i n’a fɔ sigida lakanani sariyaw bɛ ka ɲɛ, sanfɛ-nafa ani jan{1}}Life Composite Filter Media bɛna kɛ ɲininiw ni yiriwaliw sinsinnan ye.
